Support system for a gas sampler

Abstract

A support system for a gas sampler for collecting samples of gas from a plurality of laterally arranged ports and including a support rail extending outwardly from the ports to support the gas sampler for movement toward and away from said ports, an auxiliary support for the outer end of the supporting rail, a pair of laterally extending tracks and slidable couplings connecting the ends of the rail and auxiliary support to the tracks to facilitate moving the gas sampler from port to port.

I claim: 
     
       1. A support system for suspending a gas sampler from a wall having a plurality of laterally spaced ports from which samples are to be taken comprising a support rail extending outwardly from the wall for supporting the gas sampler for movement toward and away from the wall, an auxiliary support extending outwardly from the wall and connected to the support rail at a distance remote from the wall, a pair of laterally extending tracks mounted to the wall for the support of the rail and auxiliary support and slidable couplings connecting the wall ends of the rail and the auxiliary support to the tracks to permit the gas sampler to be moved from port to port. 
     
     
       2. A support system as set forth in claim 1 in which at least one of the tracks in channel-shaped to retain at least part of one of the slidable couplings and including means carried by the slidable coupling for locking the slidable coupling in a fixed position relative to the track. 
     
     
       3. A support system as set forth in claim 1 in which at least one of the tracks is channel-shaped to retain a rolling trolley within said channel and means connecting said trolley to the auxiliary support. 
     
     
       4. A support system as set forth in claim 1 in which one of the tracks is disposed above and parallel to the other of said tracks and in which the auxiliary support is a guy wire connecting the end of the support rail remote from the wall to the slidable coupling accommodated in the upper of said tracks. 
     
     
       5. A support system as set forth in claim 1 in which at least one of the laterally spaced ports is at a different height from an adjacent port and including means for suspending the gas sampler from the support rail and means for adjusting the height of the gas sampler through the suspension means. 
     
     
       6. A support system as set forth in claim 1 in which at least one of the laterally arranged ports is at a different height from an adjacent port and including a trolley accommodated for movement along said support rail, a pulley carried by the trolley, a counterweight for balancing the weight of the gas sampler and a flexible connection between the gas sampler and the counterweight which loops around the pulley for the suspension of the gas sampler and the counterweight.
